摘　　要：草甘膦是迄今为止最为重要、应用最广泛和最优秀的除草剂之一。然而,由于抗草甘膦转基因作物的广泛商业化导致草甘膦使用量迅速增长,杂草抗药性发生,这不仅对草甘膦的药效发挥和未来可持续应用造成了严重影响,而且对现代农业生产安全构成了威胁。本文通过对草甘膦的作用机理、草甘膦抗性杂草发展现状和抗性机制进行系统的总结和分析,以期为我国草甘膦的抗性研究和科学使用提供参考。Glyphosate has become one of the most important,dominant and perfect herbicide for world agriculture so far.However,the overreliance and intensive use of glyphosate alone to manage weeds has selected populations that are glyphosate-resistant.This threatens not only efficacy and future sustainability of glyphosate as a precious herbicide,but also the safety of modern agricultural production.In this review,we focus on the action mechanism of glyphosate,the current status of evolved glyphosate-resistant weeds worldwide and resistance mechanisms in different weeds.This will provide useful references for Chinese researchers in the study of glyphosate resistance and sustainable use of glyphosate in the future.
